Fuel Mixture Oil to Gas Ratio Help!!!!!

[geebt48cc]

Haze, your right about everything you said, but just remember you are using your HT in a (more so than not) flat area. I live in SW Va. with many ups and downs. At 6' 6" 260, that makes it quite a haul for these little cheapo HT's!~ So, point being, it's got to help a bit more to have just a little better than average oil in these time bombs?!~

I sent a picture of my toy loaded down. It's a 66cc slant, milled & ported.....So, far, so good at 450 miles total. I keep it in the mid twenties, and tops at 32 ish.......Mmmmmm, guess we are looking at right about 350LBS total bike and I.

ee2kS-.......and don't you think I don't think about that everytime I'm quite a few miles away from the house!!

I live in a dry climate so I run my engine (66cc) with a little higher (to some) ratio (36.57) of oil (3.5oz Amsoil Synthetic "Saber 2-Cycle Oil") to gas (One U.S. gallon of Circle-K - 87 grade). Which is also convenient because the oil comes in little 3.5oz bottles so the mixture is nearly exact every time. There are so many variables involved with these little engines that every one is different...sort of like people.

so I done one gallon at 16:1
next gallon I made is now 20:1

feels the same

so is the oil mix more for lubrication, or does running less oil like 30:1/40:1 make it run faster too and at the same time get hotter?

I got 1 speed run with the 16:1 im at 30 mph
im going to do one for the 20:1 also

and I have some 40:1 left over from another scoter I may try after I use up the 20:1
just try a small amount see how it does

I would rather have more lubrication though

-------------------------------
yes , oil in 2 stroke mix serves as a sole lubricant in 2 stroke engines, helps lessen the friction of piston rings against walls, covers with thin oily film all moving parts thus keeping down the overall temperature of the engine.
So, it is up to each one of us to work out what we want and need from our little HT and to find optimal ratio .
Personally, I think that 16:1 is a bit of overkill for breaking in but again as someone said, these are cheap and cheerful units and it is better to be on a safe side and go along tried guidelines, even if there is a bit smoke and less power output.
I always mix fresh mix before every ride, and never use any unused mix older then a week. Calibrated 2 litre bottle for mix and measuring cup for oil, small funnel and my phone calculator are the essential parts of my 2 stroke mixing kit - regardless of the amount of the mix, I just need to remember what is the correct ratio lol.

I was told even though 16:1 has more oil its actually running leaner as the oil displaces the gas

I think im going to stick with 25:1
im on my 2nd gallon of that
performance feels the same as 16:1 but I didnt want to be too lean
Im using a good brand of oil, motul and 87 pump gas
I usually keep on hand 1-2 gallons already mixed

I run mine at 50:1 i have 26cc

oil ratio chart

This chart might help.

I just started running 3oz of AmsOil synthetic for 40:1 but I think I may back off to 3.5oz for (36:1).

I've got around 3000 miles on my HT. I broke it in with the Wal-Mart house brand (think it's called Tech 1) I use a 1 gallon gas can. 1 bottle to 1 gal. is 16:1 After 1 can i started mixing 1/2 bottle to 1 gal.= 32:1 Works great, very little to no smoke, engine runs cool with good power, and it's dirt cheap. I know there are very good (and very expensive) oils out there, but is that expense justified on a cheapo China girl? I'll stick with my choice and see how it ends long-term.

Not sure about that mix, one bottle to one gallon is actually 40:1.
128/3.2 = 40. My boss used to race gocarts at 40:1 for years and never had problems. Two bottles to the gallon is 20:1. Perhaps your bottles are bigger?

Sounds like PH is buying 8 oz bottles of oil.
